Definitions

  • the present invention relates to a balloon catheter that is inserted into a stenosis site or an occlusion site formed in a blood vessel, a bile duct, a pancreatic duct, or the like and that dilates the stenosis site or the occlusion site to secure flow of blood, bile (biliary fluid), pancreatic juice, or the like.
  • a balloon catheter that is inserted into a stenosis site or an occlusion site formed in a blood vessel, a bile duct, a pancreatic duct, or the like and that dilates the stenosis site or the occlusion site to secure flow of blood, bile (biliary fluid), pancreatic juice, or the like.
  • a balloon catheter mainly includes a balloon that is a dilation body, an outer tube that is secured to the proximal end of the balloon, and an inner tube that is inserted inside the balloon and the outer tube.
  • a balloon catheter that reduces the frictional resistance between the balloon catheter and the blood vessel, the bile duct, the pancreatic duct, or the like by coating a coating agent on the balloon catheter (see Japanese Patent No. 5330506 , for example) .
  • a coating agent with low concentration and a coating agent with high concentration are coated in multi-layers so as to reduce frictional resistance between the balloon catheter and the blood vessel, the bile duct, the pancreatic duct, or the like and so as to suppress drop in manipulability of the balloon catheter when some of the coating agent comes off during a procedure.
  • the coating agent is coated on the entire surface of the balloon, the balloon disadvantageously slips in the front-rear direction when the balloon is dilated in the stenosis site or the occlusion site.
  • the coating agent is coated in multi-layers, the problem of the coating agent coming off during procedure is not resolved.
  • the coating agent comes off and the manipulability of the balloon catheter disadvantageously drops.
  • the coating agent is coated in multi-layers, the process of manufacturing the balloon catheter is lengthy and, as a result, the cost to manufacture the balloon catheter is disadvantageously high.
  • the balloon catheter 10 is used to treat, for example, a stenosis site or an occlusion site that is formed in a blood vessel, a bile duct, a pancreatic duct, or the like.
  • the balloon catheter 10 mainly includes a balloon 20, an outer tube 30, a connector 40, an inner tube 50, a tip 60, and a reinforcement body 70.
  • Fig. 1 illustrates a dilated state of the balloon 20.
  • the balloon 20 that dilates a stenosis site or an occlusion site is a member formed of resin and includes a distal end attaching portion 22 on the distal end side and a proximal end attaching portion 23 on the proximal end side.
  • the distal end attaching portion 22 is secured to the distal end of the inner tube 50 and to the tip 60, and the proximal end attaching portion 23 is secured to the distal end of the outer tube 30.
  • the distal end attaching portion 22 is secured to the distal end of the inner tube 50 through the tip 60, the arrangement of the distal end attaching portion 22 is not limited to the above and the distal end attaching portion 22 may be interposed between the distal end of the inner tube 50 and the tip 60. Furthermore, in Fig. 1 , although the proximal end attaching portion 23 is secured to an outer periphery of the distal end of the outer tube 30, the arrangement of the proximal end attaching portion 23 is not limited to the above and the proximal end attaching portion 23 may be secured to an inner wall of the distal end of the outer tube 30.
  • Fig. 2 illustrates a diagram cut along section II-II of Fig. 1 . As illustrated in Fig.
  • the balloon 20b folded around the outer periphery of the inner tube 50 includes a trunk portion 24 that covers the outer periphery of the inner tube 50, three wing portions 26a that are bent in a fixed direction so as to cover the outer periphery of the trunk portion 24, and three valley portions 28a formed at the roots of the wing portions 26a when the wing portions 26a cover the outer periphery of the trunk portion 24.
  • the three wing portions 26a comprise the smooth portions 90b and the three valley portions 28a are formed by the rough portions 80c. Accordingly, when the balloon 20b is folded around the outer periphery of the inner tube 50, the plurality of valley portions 28a that are formed by the rough portions 80c can be easily positioned between the inner tube 50 and the smooth portions 90b.
